The reaction that describe an acid an acid- base neutralization reaction is
Be(OH)2 + H2SO4 = BeSO4 +2 H2O
Neutralization reaction involve an acid and a base reaction whereby the acid neutralization the base. for the reaction above Be(OH)2 is the base while H2SO4 is the acid thus H2SO4 neutralizes Be(OH)2 to form BeSO4 and H2O
<h3>Procedural steps are: - </h3>
- On a small scale, the reaction is carried out by combining the alcohol, the haloalkane, and the phase transfer catalyst in a conical vial.
- To start the reaction, sodium hydoxide (base) is added.
- To prevent solvent evaporation, the reaction flask is covered and stirred during the reaction.
- TLC monitors the reaction's progress to ensure that no time is wasted.
- To remove any remaining water, the reaction solution is dried over calcium chloride.
- Column chromatography is used to purify the product, and evaporation is used to collect it.
<h3>What is Catalysis?</h3>
Catalysis is the process of boosting the pace of a chemical reaction by using a catalyst. Catalysts are not consumed in the reaction and so survive it.

Answer:
Positive, Negative
Explanation:
The charge of an amino acid is dependent on pH values of their pKa's. At pH 7, Basic amino acid will be positive because they have pH values below their pKa's while an R group amino acid will be negative
